What is image retention, or image burn in?

Image retention is when an image temporary or permanently remain or "burn" onto the LCD/LED panel. This happens if the image on the screen is displayed for an extended period, up to several hours without changing display, without screensaver or turning off the display.

The liquid crystal used in display technology such as LCD/LED monitors, large format display or digital signage is driven by electrodes. If the same display is remained at the same position for a long time, electric charge driving the electrodes can cause liquid crystal to build up and remain in one position, leaving a mark. This is image retention.

This mark or residue as a result of image retention is usually a shadow, or faint outline of the previous static image that was being displayed.

Depending on how long the static image remained before image retention occurred, the shadow or outline "burn" onto the display can be a permanent or temporary. This is due to the nature of liquid crystal technology and is not considered as product defect.

To avoid image retention, please activate the power management function to let the LCD/LED monitor, large format display or digital signage go into "sleep mode", or turn on screensaver after short period of inactivity. Alternatively, can use animation to avoid same display is remained for a long period of time. Certain BenQ monitor and large format display comes with built in power saving function. Please check the user manual of your BenQ monitor or larger format display for more information.

How many kinds of screens for a projector?

There are 3 kinds of screen on the market. We can differ them from the reflection rate for Matte, Beads, and Pearl. Matte Audiences watch the image for the biggest angles from the screen. No matter the projector is on the ceiling, table or on the ground, the color is rich, even and smooth. Beads It is regression. Audiences watch the image for the smallest angles from the screen. You should located audiences to stay in a limit area to have completed image. Pearl (granule) Granule makes reflection to a special direction with middle visual angle for the screen. It is more suitable for a projector which is on the ceiling. You should take care for the correct direction.

170

171

Can I use projector in smoke and dusty environment?

In locations with excessive humidity, dust or cigarette smoke the optical components may get contaminated. This would cause darkening of the image and shorten the lifespan of the projector. We strongly suggest not using the projector in environments with excessive humidity, dust or cigarette smoke.

171

172

What's different between real resolution and supported resolution?

The resolution is the pixel quantity in the image. For an example, if the resolution is 1920x1080, that means there are 1920 pixels in the horizontal and 1080 pixels in the vertical. There are 1920x1080=2,073,600 pixels in the image. The real pixels depend on the resolution of a DMD-chip. Even though the projector has real DMD chip with 1024 x768, but it can support to play the 1280*800 or other different timing via DDC IC and software translatation. Then the 1024 x768 is the real resolution and the 1280*800 or other different timing is supported resolution.

173

What is a dead/bright/dark pixel?

Synonymous in effect, a dead pixel is one that does not properly change colors - it is stuck to white. A stuck pixel is one which continually displays the same color, no matter what is on the screen. Many manufacturers will not fix/replace an LCD unless a minimum number of pixels are stuck (usually 3 or 5). As technology improves, dead pixels are also becoming rarer.

How to change the lamp?

Please follow the steps below: 1. Turn off the main power source and have the cable pulled out 2. Loosen the screws located under the cover of the light bulb with the screwdriver. If the bulb was just finished using at this moment, please wait for 45 minutes to ensure that it has already been cooled down. 3. Loosen the screws that fasten the light bulbs. Hold the handles of both sides of the bulbs, take out the screws carefully. 4. Put into the new bulbs and fasten the screws that were originally used to hold the light bulbs. 5. Fasten the cover of the light bulbs below the projector with the screws 6. Please do not turn on the power before covering the light bulbs with the cover because of the safety consideration.

175

176

Why does projector have some noise?

The noise that users hear normally came from:
1. Color wheel: The speed of the color wheel is around 6000 rpm. Smaller projector will have a noisier color wheel. Abnormal spinning noise of the color wheel will be more disturbing and alarm. Sometimes its even generates abnormal images.
2. Projector fan: The purpose of the fan is ventilation and heat dissipation. Normally there will be one inlet fan in front and two outlet fan at the back. One of the fans is mainly to cool down the light bulb. An intelligent fan control system is used to control the heat dissipation of the projector by detecting the thermal resistance and automatically adjust the speed of the fan. As a result, users might notice a sudden change of the fan spinning noise. This is a normal adjustment which has nothing to worry about. After a long period of usage, the projector fan might start to generate abnormal sound or even stop spinning. When this happens, we suggest users stop using the projector and send it to BenQ maintenance centers for inspection.

176

177

My projector powers off erratically. What is causing this?

1. The front lamp cover is not correctly attached. Correctly attach the front lamp cover.
2. The temperature inside the projector is extremely high. Check that the ventilation holes are not blocked.
3. The ambient temperature is too high (above 35°C / 95°F). Make sure the projector is operating under normal operating conditions (clean, relatively dust-free environment) the lamp will have the greatest likelihood of lasting through its entire rated lamp life.

What is the difference between DLP projectors and LCD projectors？

DLP (Digital Light Processing) is the exclusive technology of the Texas Instruments, adopting the principle of mirror reflection to present images. It has the advantages of full digitization, high contrast, fine image, small volume, and long-lived life, etc. Generally speaking, LCD projectors are better in color saturation and color temperature. However, the shortcomings are that they are very big and hard to carry and LCD will become worn out after using a period of time so its maintenance cost is relatively high.

189

190

Why is the lamp is not as bright (or dimmed) after using for a period of time?

The life-span of light bulbs used in the projector can be categorized as 1500, 2000, and 3000 hours. It is a normal phenomenon if The brightness degree declines a little with the span of service time period. You can get a better brightness degree by adjusting OSD.

190

191

What reason will cause lamp to breakdown?

If the projector is continuously used for a long period of time (more then 4 hours) or having poor heat disputations when using, the life spend of the light bulb will be shortened due to the heat unable to dispute normally. The performance of the projection screen brightness will be reduced significantly. Suggest changing the light bulb.

191

192

How long is the life-span of the light bulbs of the projector?

The light bulbs used are Philip UHP bulbs with high capacity and efficiency. Experiments prove that the life-span of UHP bulbs can be approximately 1500~2000 hours. After the use hours are met, the efficiency of the light bulbs declines to 70%. Recommend that consumers must change light bulbs after the use hours reach its limit. The built-in time recorder in the projector will count the accumulated use hours and restrain users from turning on machines when the limit of the use hours are reached to protect the safety of users and machines.

192

193

How to cleaning the lens?

For fingerprints and other soiling that are difficult to remove with a dry cloth, use a designated glass cleaner which has been moistened in water and then use a dry cloth to dry it off. The projection lens surface has a special coating. Do not use detergents or solvents on the surface.

193

194

The lamp is not on but the fan remains running, what is happening?

This might cause if the projector was not properly shut down, and you attempt to restart it soon thereafter, the fan may run for a few minutes to cool it down properly before you can restart. You will have to wait before you can press Power again to start the projector after the fans stop.

198

Why are some TV boxes unable to display on LCD monitor?

That is because some LCD models have low refresh rates at 50Hz (Example : Samsung), and some TV boxes do not have function to switch from 50Hz to 60Hz. The refresh rate is just around 50Hz. (Example: 49.9Hz) When these conditions match, the monitor will display in black. In theory, the display will function normally only when the refresh rate of the TV box is higher than the LCD.

198

199

What is Ghosting/Blurring and Why Does It Happen?

An issue that mostly affects games, ghosting is due to pixel response. If an LCD does not update a pixel (or in the case of screen, a lot of pixels) fast enough, the old image is still super-imposed when the new one is applied. Ghosting is easy to see with a dark object on top of a light background. As technology gets better, pixel response times are decreasing, removing ghosting as an issue.

199

200

Why is my screen blurry/stretched when I change resolution?

Unfortunately, as LCD monitors are pixel based, changing from a monitor's native resolution creates problem. The monitor tries to mathematically extrapolate the resolution to the entire screen. As such, each monitor comes with a 'native resolution' which is its intended use. For 99.99% of cases this will be enough for a consumer.

200

201

What is “out of range” in LCD?

When the monitor display “out of range” that means the setting is unable to synchronize with it. This is due to the setting of resolution too high or unsupported. In this situation, please enter OSD control panel -> display -> setting -> change the resolution of the display that support by the monitor. The go to control panel -> display -> setting -> advance -> monitor -> change the frequency to 60 Hz.

201

202

I-key and geometry key unable to function after using DVI connection

When you use digital interface for the display, the signal transmitted is in digital format. Therefore the signal transmitted is very accurate. Thus, there is no need for auto and geometry adjustment. That is the reason for the display to be in gray. Besides that, the refresh rate of LCD monitor is only 60Hz, which is one of the differences between digital and analog interface. Please do not worry as it is a normal phenomenon.

202

203

MVA Panels

V and A stand for "Vertical Alignment". This means that when the crystals are in the isolated state they stand vertically. This is the same as IPS panels. What is special about MVA panels is the fact that each cell is sub-divided into several areas (or domains). The M stands for "multi-domain". These are organised in sloping angles to each other. No further intervention is necessary because any errors that occur correct each other. So the light yield is maintained. Contrast and representation of colours remain constant. MVA cells can also react considerably quicker than IPS cells. However black is not as rich as with IPS.

203

204

Viewing angle

The viewing angle is the display's visible field. If one were to imagine a vertical line in the centre of the image and to pivot up and down and to the right and to the left from that point, then that is the viewing angle. This value is calculated technically by measuring the contrast until it falls below a certain value. Usually a contrast value of 10:1 is used. But some companies also use a value of 5:1 to achieve higher values. This is not serious in comparison terms because it is a conscious falsification of the values. Certification under ISO 13406-2 also offers clarity here because the viewing angle classes are divided up and the use of a defined measurement method are proscribed. Working ergonomically requires a viewing angle of at least 60°/60° (right/left) horizontally and 45°/45° vertically (up/down). If only two values are specified for horizontal and vertical, the values for right and left, and for horizontal and vertical are added together. If this were the case then this would provide a viewing angle of 120° horizontally and 90° vertically.

204

205

Contrast

Contrast is the ratio between the light intensity of the brightest and the darkest point of an image. High contrast values improve readability and ergonomics. A display should in all instances attain contrast values of 250:1. This is a point on which LC displays are clearly superior to CRT monitors. Good CRT monitors have values of about 90:1.

205

206

Response time

The so-called response time refers to the time it takes for a liquid crystal panel to go from total white to total black and then back again (Rise Time (Tr) + Fall Time (Tf)). Broadly speaking, the response time of LCDs are slower than those of CRTs. In the past, the response time of most LCDs was between 20ms and 50ms, and the adverse effects of this relatively long interval could be noticed during playback of DVDs or when playing games that required especially quick scene changes. You would, for example, find that fast-moving objects would cause ghosting, particularly when black objects passed through a bright-colored background.

Image frequency and the human eye

The human eye will perceive a series of sequential images displayed at a frequency of 30Hz (30 images, or frames, per second) as continuous, as is the case with movies (24 frames per second). Screen images displayed at 60Hz will offer even more comfortable viewing, but careful scrutiny will reveal a slight sense of "flickering", as is the case with the NTSC television standard (which displays at 60 frames per second). According to standards set by VESA (Video Electronics Standards Association), the frequency necessary to achieve flicker-free display with a CRT is 72Hz. Most VGA cards and software applications, in order to accommodate the use of CRT monitors, have working frequencies set at 75Hz. In the past, the LCD monitors with 16ms response time that predominated in the market supported frequencies only up to 63Hz (1/0.016), making their display performance inferior to that of CRT monitors. Avid gamers therefore continued to use CRT monitors.

Lightning fast response time: 12ms

BenQ's new FP767-12 and FP783 LCD monitors represent a breakthrough, having reduced response time to a mere 12ms. The LCD panels used in them can support a display frequency of 83Hz (1/0.012). Coupled with BenQ's sophisticated electronic design, this allows BenQ's LCD monitors to achieve the full performance potential of their hardware, enabling them to fully support the 75Hz working frequency of VGA cards, as well as their targeted applications. The amazingly fast 12ms response time made possible by BenQ LCD monitors provide exceptionally fluid video without flickering and other visual artifacts. The result is that dynamic game and movie scenes displayed at 75 frames per second appear without breaks, offering display quality fully the equal of a CRT monitor's.

Gaming

Today's most popular games-whether racing titles such as 2 Fast 2 Furious, first-person shooters like Half-Life: Counter-Strike or Unreal Tournament 2, or sports games such as NBA Live 2004-demand speed and fast responses. Taking 2 Fast 2 Furious as an example, if your LCD's response time is slightly slow, you may notice a momentary blurring of the track or even a double-image of your racecar when you accelerate to shoot past another racer. Not only is the visual experience of the game marred, but these effects may even lead to a mistake in driving judgment that could mean the difference between victory and defeat.

Moreover, when you are playing a first-person shooter game such as Counter-Strike, if the time between discovery of an enemy combatant and firing your weapon is delayed by even milliseconds, it can mean the difference between survival or adding yourself to the bodycount. Smart gamers know the advantage of having an LCD monitor with a fast response time. And BenQ's 12ms response time give you that crucial edge at the moment of truth!

Today's popular games that demand ultra-fast display response times:

Brightness

Brightness is the emitted luminous power over a specified area. Brightness is another point, on which LCD monitors are superior to CRT devices. Traditional monitors create approx. 80 to 100 cd/m? (candela per square metre). In the case of LC displays, values below 200 cm/m? are not acceptable and are only common on outdated panels.

VGA Connection

VGA connections are still standard even for an LC display. It consists of a 15-pole mini sub-d plug or a socket. However certain restrictions arise from the use of the analogue signal standard that was actually used for CRT monitors. The digitally created image in the computer is converted in the graphics card into an analogue signal. If you use this VGA connection analogue signal for a digital LC display, then transducer electronics at the display input must cater for conversion back into digital signals. Two problems occur with this:

Conversion losses

The image is not so optimal as compared with direct, digital control. It can otherwise be the case that subsequent adjustments are necessary at regular intervals every few months on a regular basis. This is generally executed via the OSD or an automatic function..

Limitation to specific operating modes

These days a CRT monitor is usually a multi-scan monitor. This means: it can be operated within the limits of its horizontal and vertical frequency, even in non-standard modes. However LCD screens are multi-frequency monitors. It only works together with certain modes (listed in the handbook).

208

209

Digital connections

Now the market has decided on a standard: the DVI standard. The old interface variants will disappear from the market over time. In future there will be more "dual input" devices that provide both standards. At some point DVI graphic cards will become standard equipment for PCs and people are already looking at the possibility of equipping CRT monitors with a digital interface and therefore only changing the signal from digital to analogue inside the monitor.

Important quality criteria

ISO 13406-02 is the T?V (German Technical Monitoring Association) test standard for ergonomic testing and includes the testing of a screen's ergonomic characteristics. ISO 13406-2 has been especially developed for evaluating LC displays. CRT screens have the ISO 9241-3-7-8..

Important criteria for evaluating an LC display include:

:: Display luminance

:: Contrast

:: Reflections

:: Consistency of luminance and colours

:: Font analysis

:: Pixel errors

:: Flickering

LCD (Liquid Crystal Display)

LC based projection systems work on the basis of the anisotropic characteristics of liquids. This means that a liquid crystal cell works like a light valve that can allow or block the flow of light through the use of an electric current.

The use of polarised light is a further pre-requisite for projection systems on a LC basis. Because only polarised light can be usefully controlled.This is guaranteed by the use of polarisation filters that have the characteristic of allowing light with a certain oscillation level to pass through.

In the past amorphous silicon was used as a medium. Today we use polycrystalline silicon, a mixture of pure and amorphous silicon. Panels made of poly-silicon TFTs (Thin Film Transistors) are smaller. The typical size of the panels is 0.7"; 0.9"; 1.3", and 1.8". The panels' sides have a relationship of 4:3 for an SVGA or XGA resolution and 5:4 for an SXGA. Occasionally you can now get real 16:9 panels.

In order to achieve a colour picture, the image must be projected in the three basic colours of red, green and blue. All other colours are mixed from these. Typical LC projectors today use 3-chip technology, with which one panel is required for each of the three basic colours.

White light is split up using dichromate mirrors and thrown onto the LC panel in which the corresponding colour fraction of a picture is created.The colour fractions are joined together in the prism to a colour image and projected onto the image screen using the lens. The LCD technology has the disadvantage that the lamp light must be driven past onto the control transistors that are located behind each LCD cell. These are necessary to switch the cell but do disturb the flow of light. Newer techniques try to optimise the flow of light using micro lenses. This is a lattice-shaped organisation of small lenses that are laid out immediately behind the LC panel. Each pixel has its own lens. The lenses narrow the light and direct it to the transistor's control conduits.

Advantages of LCD Technology:LCD technology is currently more cost effective than DLPTM.LCD technology has fewer mechanical components.

Disadvantages:LCD projectors can not be manufactured as compact as wanted. The higher the resolution the lower the light yield.

With DLP projectors the projection lamp light is projected using a fast rotating RGB colour wheel (RGB = red, green, blue) onto the DMD (Digital Mirror Device) chip. The mirrors located on the chip reflect the light through the lens onto the screen. With the aid of the fast rotating colour wheel - which consists of 1/3 red, green and blue - the colours on the screen are mixed and natural colours produced. Some colour wheels also have a transparent segment for producing a lighter image.

The Texas Instruments DMD chip lies at the heart of the DLP? technology. More than 500,000 movable mirrors are laid out on a chip the size of a fingernail. Each one of these mirrors is attached to a torsion joint, can adopt two positions and can be controlled directly.

The principle is simple. Light falls from the lamp, through the colour wheel onto the chip. Depending on its tipped position, the light for each pixel is either directed to the screen or completely absorbed in the projector by the projection optical system. This is why DLP? projectors have higher contrast values.

Because the mirrors only know two positions but for natural portrayal many brightness levels are required, we use a trick: pulse-wide modulation.When displaying a dark pixel the mirror only stays in the light position for a very short time. You lengthen the light impulse to display a light pixel.

Advantages of DLP? Technology

- Lower pixel structure and so excellent video quality- The higher the resolution, the higher the light yield- No convergence problems (the three colours are projected without errors, there are no coloured edges)- Better contrast and therefore better picture definition

I couldn't see anything on my LCD monitor after I connected the power, what should I do?

Check the energy saving mode; press any key or move the mouse to quit the energy saving mode. Check if there are any bent or missing pins in the monitor connector. If there are, contact your dealer.

213

214

Why can't BenQ FP551 adjust optimal brightness function?

The FP 551 uses Hosiden Panel. Due to the fact that the original manufacturer design of the Hosiden Panel driving current is limited to 5mA, when the contrast is too high, a change in the brightness is not apparent. After having conferred with Hosiden, the driving current range has been modified to a larger margin and the change in brightness will become noticeable after adjustment. In order to achieve a noticeable change in brightness, we recommend the following: Adjust Contrast to optimal range around 25~35, then adjust Brightness. There will be a distinct change in brightness.

215

How do I set up the remote mouse?

Most projectors can emulate a mouse when connected to a computer using one of the remote mouse cables (serial, PS/2 or Mac ADB).

Connect the mouse cable between the projector and the computer.

Note: For a PC laptop, the best choice is the PS/2 connection. For Mac, use the ADB cable.

Check the mouse driver in Windows:

Windows 95/98: In the Control Panel, click on Mouse and check the driver. The driver should be set on either Standard PS/2 or Standard Serial depending on which cable is used.

Windows 3.1: In Windows Setup, the mouse driver should be set to Microsoft or IBM PS/2 mouse.

Turn on the devices: with the mouse cable and mouse driver set up, turn on the projector and restart the computer.

215

216

I have a new PC laptop and the projected image is too big for the screen. What can I do to change this?

Your Laptop may have a separate control for external display. In Windows, go to Control Panel, Display and click on PC, Advanced, CRT. In the CRT settings, change the display to either 800x600 or 1024x768 to match the projector.

What is LED backlight?

LED backlighting in color screens comes in two flavors: white LED backlights and RGB LED backlights. White LEDs are used most often in notebooks and desktop screens, and in virtually all mobile LCD screens. A white LED is typically a blue LED with broad spectrum yellow phosphor to give the impression of white light. Since the spectral curve peaks at yellow, it is a poor match to the transmission peaks of the red and green color filters of the LCD. This causes the red and green primaries to shift toward yellow, reducing the color gamut of the display. RGB LEDs consist of a red, a blue, and a green LED and can be controlled to produce different temperatures of white. RGB LEDs for backlighting are found in high end color proofing displays such as HP DreamColor LP2480zx monitor or selected HP EliteBook notebooks, as well as newer consumer grade displays such as Dell's Studio series laptops which have an optional RGB LED display. RGB LEDs can deliver an enormous color gamut to screens. When using three separate LEDs (additive color) the backlight can produce a color spectrum that closely matches the color filters in the LCD pixels themselves. In this way, the filter passband can be narrowed so that each color component lets only a very narrow band of spectrum through the LCD. This improves the efficiency of the display since less light is blocked when white is displayed. Also, the actual red, green, and blue points can be moved farther out so that the display is capable of reproducing more vivid colors. CCFL backlighting has also improved in this respect. Many current LCD models, from cheap TN-displays to color proofing S-IPS or S-PVA panels, have wide gamut CCFLs representing more than 95% of the NTSC color specification.

428

429

What is IPS display?

IPS stands for In-plane switching. In-plane switching was developed by Hitachi Ltd. in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels at that time.[6] Its name comes from the main difference from TN panels, that the crystal molecules move parallel to the panel plane instead of perpendicular to it. This change reduces the amount of light scattering in the matrix, which gives IPS its characteristic wide viewing angles and good color reproduction.[7] Initial iterations of IPS technology were plagued with slow response time and a low contrast ratio but later evolutions have made marked improvements to these shortcomings. Because of its wide viewing angle and accurate color reproduction (with almost no off-angle color shift), IPS is widely employed in high-end monitors aimed at professional graphic artists, although with the recent fall in price it has been seen in the mainstream market as well.

429

430

What is MVA display?

MVA stands for Multi-domain vertical alignment. Multi-domain vertical alignment was originally developed in 1998 by Fujitsu as a compromise between TN and IPS.[citation needed] It achieved pixel response which was fast for its time, wide viewing angles, and high contrast at the cost of brightness and color reproduction. Modern MVA panels can offer wide viewing angles (second only to S-IPS technology), good black depth, good color reproduction and depth, and fast response times due to the use of RTC (Response Time Compensation) technologies. When MVA panels are viewed off-perpendicular, colors will shift, but much less than for TN panels. There are several ""next-generation"" technologies based on MVA, including AU Optronics' P-MVA and A-MVA. Analysts predicted that MVA would dominate the mainstream market, but the less expensive and slightly faster TN overtook it. The pixel response times of MVAs rise dramatically with small changes in brightness. Less expensive MVA panels can use dithering and FRC (Frame Rate Control).

What do P, NP, FS, O in timing table mean?

P stands for “preset mode” and is the preferred setting. NP is ""Non Preset"" mode that the monitor supports and image can be displayed. FS: Fail Save Mode. The image can still be displayed but may not be able to displayed correctly because it’s out of range. ""Out of Range"" will be shown. O: Out of Range. The monitor does not support, and no picture would be shown. Therefore, the resolution with P is the preferred setting.

What is Display Port?

DisplayPort is a digital display interface standard produced by the Video Electronics Standards Association (VESA). The specification defines a royalty-free digital interconnect for audio and video. The interface is primarily used to connect a video source to a display device such as a computer monitor or television set. The first version 1.0 was approved by VESA on May 3, 2006. Two updated revisions have since been approved starting with 1.1a on April 2, 2007 followed by the current standard 1.2 on December 22, 2009. DisplayPort is designed to replace Digital Visual Interface (DVI) and Video Graphics Array (VGA), as well as replace internal digital LVDS links in computer monitor panels and TV panels. DisplayPort can also provide the same functionality as HDMI but is not expected to displace HDMI in high-definition consumer electronics devices. Most of the DisplayPort supporters are computer companies including Apple, Dell, HP, Lenovo, Fujitsu, Toshiba and Acer, some of which have released several computer monitors that support DisplayPort and some also with HDMI. In December 2010 it was announced that several computer vendors and display makers including Intel, AMD, Dell, Lenovo, Samsung and LG would stop using LVDS from 2013 and legacy DVI and VGA connectors from 2015, replacing them with DisplayPort and HDMI. Likewise, HP expects that DisplayPort will completely displace VGA and DVI by 2013. However, many are still using those connectors, so it doesn't seem to have much effect right now. Most laptops still have HDMI and legacy VGA ports, but not DisplayPort or DVI. In 2010, BenQ launched BL2201PT, BL2201PU, BL2400PT & BL2400PU that support DP 1.1a.

Explanation for different sound channel.

1. Dolby Digital Mono: Mono is the term used to describe sound that is only from one channel. Mono is used widely in talk radio and mobile communications since stereo doesn't really provide any practical advantages in these situations. Recording in mono is less complicated compared to recording in stereo. Most hand-held voice recorders can only record in mono. 2. Dolby Digital Stereo: stereo uses 2 or more channels to provide an experience much like being in the same room where the sound was created. Stereo is essential for broadcasting and listening to music since Mono provides inadequate sound quality. 3. Dolby Digital Surround: Dolby Digital Surround Sound is an advanced form of digital audio coding that makes it possible to store and transmit high-quality digital sound efficiently. It gives a listener/viewer a more realistic feeling. 4. Dolby Digital 5.1 Surround Sound: Dolby Digital 5.1 Surround Sound is an audio coding technique capable of delivering sound with five discrete full-range channels--left, center, right, left surround, and right surround--plus a sixth channel for those powerful low-frequency effects that are felt more than heard in movie theaters. This is commonly known as the subwoofer. The subwoofer needs only about one-tenth the space of the others and is referred to as a "".1"" channel. Therefore, the entire group of channels is named Dolby Digital 5.1 Surround Sound.

451

What is Stereoscopy Display?

Stereoscopy (also called stereoscopic or 3-D imaging) refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. Both of these 2-D offset images are then combined in the brain to give the perception of 3-D depth. Three strategies have been used to accomplish this: have the viewer wear eyeglasses to combine separate images from two offset sources, have the viewer wear eyeglasses to filter offset images from a single source separated to each eye, or have the lightsource split the images directionally into the viewer's eyes (no glasses required; known as Autostereoscopy).

Passive Panels

With passive panels the pixels are directed onto the screen using a matrix to guide them. A special control component takes over addressing each pixel according to its columns and lines. This is called DSTN technology (DSTN = Dual Scan Twisted Nematic). However passive technology requires a payback in terms of picture quality. For these screens the contrast stays weaker, the brightness distribution is not as consistent by far when compared to the expensive TFT technology. DSTNs react very slowly. This can be seen in typical streaking and smearing effects for fast movements, for example the mouse pointer. This technology is out of date and is hardly ever used any more.

497

498

Active Panels

With TFT displays (TFT = Thin Film Transistor), also called active matrix, the light transmitting capacity of each pixel is controlled by a single transistor. The pixels can therefore be operated individually and addressed very quickly, which in turn guarantees perfect display of moving images. TFT screens have a high display quality because of their active drive. The advantages of this technology are strong contrast, consistent brightness distribution and above all short response time. In addition they have better angle of view than passive displays.

498

499

TN+Film

This method is the simplest and therefore cheapest to put into practice. A film is attached to the surface of the DSTN panel to raise the angle of view. The other characteristics remain the same.

LCD principles

The functionality of LCD (Liquid Crystal Display) screens is based on the special physical properties of liquid crystals. Their rod shaped molecules arrange themselves similarly to the molecules of crystals - always uniformly and in one particular direction. Yet liquid crystals are not set in this orientation, but behave like a liquid: They can be manipulated by applying an electric voltage. The layers of the liquid crystal molecules can therefore be longitudinal or diagonal to the polarising direction of the light and thereby have a varying effect on the course of light waves. This principle can also be simplified if you imagine a light valve controlled by an electrical voltage.

An LC display consists of two polarising filters, a control layer, the respective colour filters and the liquid crystal layer.

The light from a background lamp hits an initial polarisation membrane so that only a specific plane of polarisation of the light reaches the liquid crystal layer. Without any external electrical influence the liquid crystal molecules arrange themselves in a screw-like shape between the two vertically aligned polarising filters and the directional structure imposed as a result. The light follows this orientation and is rotated by 90 degrees. The second polarising filter only allows light with this rotated polarisation through. The light valve is open - as a result the controlled pixel lights up.

If an electrical voltage is applied, the liquid crystal molecules orientate themselves along the field lines. The 90' screw is lifted up, the LC molecules appear parallel to the incident light and allow it to pass through without altering the polarising direction. The un-rotated light hits the second, rotated polarising filter and is blocked. As a result the corresponding pixel remains dark.

The intensity of the departing, visible light can be controlled by means of the voltage applied to the crystal layer and the polarised light rotated to a greater or lesser extent as a result.

The voltage is continuously on so that the image does not have to be rebuilt constantly. The great advantage of this is that LC displays do not flicker, even when they are controlled at low refresh frequencies (e.g. at 60 Hz).
